Answer:
y = 2x + 5
Step-by-step explanation:
First, find the slope using rise over run, (y2 - y1) / (x2 - x1)
With this information, we can create 2 points: (2, 9) and (5, 15)
Plug in the points:
(15 - 9) / (5 - 2)
6 / 3
= 2
Plug in the slope and a point into y = mx + b, and solve for b:
y = mx + b
15 = 2(5) + b
15 = 10 + b
5 = b
Plug in the slope and b into the equation:
y = 2x + 5 is the equation of the line
12 x (4.2 x 10^6) =
5.04 x10^7

Answer:
x = 15
Step-by-step explanation:
If ABC similar to EDC then we can use the similarity ratio to find the value of x
32/(3x-5) = 56/(5x-5) cross multiply the fractions
160x - 160 = 168x - 280 export like terms to the same side of the equation
280 - 160 = 168x - 160x
120 = 8x divide both sides by 8
15 = x
All we need to do is to find out how many 25 cm cake tins will fit along the 70 cm edge (70 cm because 700 mm = 70 cm).
70 : 25 = 2,8
It means that 2 and 0,8 tins will fit, which is generally 2 tins because the third one wouldn't fit.
Now we have to do the same with the 60 cm edge:
60 : 25 = 2,4
So again we'll have 2 tins along the other edge, but with less spare space.
Now we just have to multiply both edges to get the amount of the tins that will fit on the tray:
2 * 2 = 4
Answer: 4 cake tins will fit on oven tray measuring 700mm x 600mm.
